Test tube rack with inserting structure

ABSTRACT

A test tube rack with the inserting structure comprises of a top tray bridging and jointing a set of bottom tray on the bottom side as the two main parts; several rows of inserting holes for the test tubes are mounted on the top tray surface; through holes with the same apertures vertically and relatively to the said inserting holes for the test tubes are disposed on the flexible sandwich plate on the upper portion of the bottom tray set; the lower portion of the bottom tray set is mounted with the receiving cups with the same apertures extending downwards and relatively to the said through holes to allow the bottoms of the test tubes to enter and stand inside the receiving cups; when inserting, the test tubes depressed or placed gently stand with various heights for convenient selecting, temporary storing or further conducting the screening and distinguishing.

BACKGROUND OF THE INVENTION

[0001] 1) Field of the Invention

[0002] The invention herein is a test tube rack with the improved inserting structure, more especially a test tube inserting structure for a test tube rack; as the test tube being put into the inserting holes, the height of the test tube placed gently will be higher than that of the test tube depressed gently at the tube opening to make the bottom of the test tube push through the holding hole to fall into the receiving cup; therefore, by the different heights of the test tubes stood on the same tray, the selecting, temporary storing or the screening and distinguishing of the test tubes can be conducted.

[0003] 2) Description of the Prior Art

[0004] During the process of medical inspections, various bi-chemical operations or experiments, many test tubes will be examined. Therefore, the test tubes need to be placed individually to stand on the specific test tube rack for achieving the purpose of resuming, placing or arranging.

[0005] However, the conventional structure of the test tube rack, as shown in FIG. 1, consists of a metal mesh basket (10) with basket openings (11) on the top; every mesh opening (12, 13) mounted downwards can hold one test tube (20, 21) to stand inside; the examiner can select and pick up the test tubes to complete the examination for all the test tubes one after the other; during the examination, if the examiner can step by step and randomly inspect the test tubes consecutively, it is easy to distinguish which test tube (20,21) is under examination, which one is still waiting for examination, which ones passed the examination and which ones didn't; however, during the operation, the operator often comes across unexpected situations such as receiving a phone call or being asked by the colleagues to discuss cases; thus the procedure of examination is interrupted; then, as the examiner returns to examine the test tubes, he may easily forget up to which test tube (20, 21 )he was working since the test tubes (20,21) standing in the same basket, belonging to the same group, with the same type, examining purpose and height tend to get confused. Without initial and special distinguishing for the examined and unexamined test tubes, or without consistent order for randomly picking up, the confusing situation can't be prevented for sure.

[0006] Therefore, in operation, the examiner usually uses two mental mesh baskets (10) for conducting the distinguishing; that means, one basket for test tubes to be examined and the other for placing the examined ones to obviously separate the latter from the former so as to allow the examiner returned after leaving temporarily from the job can clearly distinguish the test tubes; however, using this method, two metal mesh baskets (10) are always required, which not only becomes troublesome for preparation, but also inconvenient since for occasions requiring the carrying of the test tube rack to other medical treating locations or biochemical inspecting stations for doing short-noticed examination of lesser quantities, for easy carrying, usually only one mental mesh basket will be taken; therefore, the original habit of examining two distinguishable baskets will be broken and not be substantially maintained for sure; or, in order to distinguish the test tubes (20,21) of the examined, the unexamined, the passed or not, the examiner may leave some of the mesh openings (12, 13) available for placing the test tubes (20,21) empty so as to use the gaps for distinguishing and separating the test tubes (20,21) in the basket into two groups of the examined and unexamined groups or the passed or not groups; although this method can separate the test tubes (20, 21) in the same basket, the available positions in the basket will be sacrificed and also reduce the number of examinable test tubes (20, 21) inside every basket and fail to achieve the examination quantity that each basket in every group is supposed to have.

[0007] In view of the mentioned various shortcomings of the conventional rack structure for the test tubes, the inventor of the invention herein researched enthusiastically for the improvement, after going through the process full of hardship in making innovation, finally culminated in the invention herein.

SUMMARY OF THE INVENTION

[0008] Therefore, the invention herein is to provide a test tube rack with the improved inserting structure; between the transversely superposed tray bodies, a flexible sheet mounted with holding holes relative to the bodies of the inserting test tubes; the flexible sheet is made of flexible material; the holding holes are in the shapes of starlike radiation with the diameters a little smaller than that of the bottom of the test tubes and capable of supporting the test tubes and the weight of the liquid inside the test tubes; as being put into the inserting holes, the height of the bodies of test tubes being placed gently will be higher than that of the test tubes being depressed gently on the tube openings and pushed through the holding holes and fell into the receiving cups; therefore, by the different heights of the test tubes placed in the same tray, the test tubes under examination can be selected, temporarily stored, screened or distinguished as one of the objectives of the invention herein.

[0009] Another objective of the invention herein of a test tube rack with the improved structure for inserting test tubes is to have narrow seams or grooves, mounted downwards on the two side walls adjacent to the side rims of the bridged and superposed top tray and bottom tray set, for mark labels to be inserted conveniently to indicate the examination items, dates, etc. of the test tubes in that tray so as to eliminate the preparation of the glue or the stapler for pasting or hanging the labeled notes to the test tube rack.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Referring to FIG. 1, the shortcomings of structure of the conventional test tube rack mentioned above will not be described again.

[0018] Referring to FIG. 2 of the a pictorial drawing of the entire test tube rack with the improved inserting structure of the invention herein, FIG. 3 of the pictorial exploded drawing, FIG. 4 of the top view drawing and FIG. 5 of the side view drawing, the invention herein of test tube rack with the improved inserting structure comprises of a test tube rack (100), from the bottom of a top tray (200) extending several perpendicular rods (201,202) distributed in proper distance to insert and bridge vertically to joint a bottom tray set (300); several rows of inserting holes (210,211) for the test tubes are mounted on the top tray (200) surface; the through holes (311,312) with the same apertures vertically and relatively to the said inserting holes (210,211) for the test tubes are disposed on the flexible sandwich plate on the top side of the bottom tray set (300); the lower portion of the bottom tray set (300) is mounted with the receiving cups (321,322) with the same apertures extending downwards and relatively to the said through holes (311,312) to allow the bottoms of the test tubes ( not shown in the FIGs.; referring to FIG. 1 or FIG. 4) to enter and stand inside the receiving cups (321, 322) through the inserting holes (210, 211) and the through holes (311,312) for the test tubes; the bottom tray set (300) is formed by inserting and superposing a flexible sandwich plate (310), a tray set of receiving cups (320) and a piece of flexible sheet (330); the said through holes (311,312) are mounted at the proper positions on the flexible sandwich plate (310) with the top portion of the flexible sandwich plate (310) bridging and jointing the bottom of the said top tray (200); the flexible sheet (300) is superposed between the flexible sandwich plate (310) and the tray set of receiving cups (320) with starlike and radial holding holes (331,332) mounted thereon relative to the said through holes (311,312); the center diameters of the holding holes (331,332) are a little smaller than that of both the inserting holes (210,211) for the test tubes and the through holes (311,312) on the flexible sandwich plate (310); furthermore, around all inserting holes (210,211) for the test tubes on the surface of the top tray (200), as shown in FIG. 4 of the top view drawing, the order numbers (600) can be formed by carving or printing to help the operator distinguish the arrangement positions and quantities; furthermore, the narrow seams (400) and the grooves (401), mounted downwards on the two side walls adjacent to the side rims of the bridged and superposed top tray (200) and bottom tray set (300), are for mark labels (500) to be inserted conveniently to indicate the examination items of the test tubes in that tray.

[0019] In application, as shown in FIG. 6 of the sectional view of the invention herein, as the test tubes (700) being inserted, by choosing to gently place the tube bodies, the bottoms of the test tubes (700) will not go through the holding holes (331) but be blocked and supported high by the hole rims of the holding holes (331); by gently depressing the openings of the test tubes (701), the bottoms of the test tubes (701) will push through the holding holes (332), fall into the receiving cups (321) and lower the test tubes (701); therefore, to put the test tubes (700, 701) in various heights helps the selecting, temporary storing, screening and distinguishing of the test tubes under examination; since the natural reaction of people at the moment of receiving unexpected notice or telephone call for leaving the working seat will cause attention destructed, the examiner will more likely put the picked and unexamined test tube (700) gently back to the mesh opening instead of seldom spending time to push the test tube (700) back to the lower position; otherwise, for recognized test tube (701) under no emergent situation, the examiner will carefully and naturally push them to the lower positions; helped by checking the order numbers (600) on the tray surface, after the examination being interrupted, the examiner knows for sure that he can still clearly distinguish which test tube (700) he should start with to continue the work with almost no chance of being confused by the sequential order of the examination; from that Figure, it is obviously to know that the centers of the bottoms of the receiving cups (321,322) extending downwards from the bottom of the tray set (320) of the receiving cups can be mounted with leaking holes (321A, 322A) for draining the water condensed due to the temperature difference and sank into the receiving cups (321, 322).

[0020] In summation of the foregoing sections, the invention herein of a test tube rack with an improved inserting structure, more convenient for the selecting, temporary storing or conducting the screening and distinguish the test tubes, substantially superior than the conventional test tube rack in terms of enabling the clear distinguish for starting from the correct test tube to continue the interrupted examination and the convenience of inserting the mark labels, not revealed for the public usage, fully complies with all new patent application requirements and is hereby submitted to the patent bureau for review and the granting of the commensurate patent rights.

[0021] What needs to be indicated is that the foregoing sections mentioned above relate to the preferred embodiment of the invention herein; therefore, the functions of any modification based on the idea of the invention herein not beyond the description and drawings included in the spirit should be limited within the scope of the invention herein.
